Understanding Keratoconus: Causes, Symptoms, and Treatment Options at Valley Laser Eye Centre

Keratoconus is a progressive eye condition characterized by the thinning and bulging of the cornea into a cone-like shape, resulting in distorted vision, sensitivity to light, and frequent changes in eyeglass prescription.

Investigating the Causes and Risk Factors of Keratoconus

Although the exact cause of keratoconus remains unknown, researchers believe that a combination of genetic and environmental factors contribute to its development. Some possible causes and risk factors for keratoconus include:

  • Genetic Predisposition: Studies suggest that keratoconus has an underlying genetic component, with individuals having a higher risk of developing the condition if a family member is affected.
  • Frequent Eye Rubbing: Persistent eye rubbing, often aggravated by allergies or irritation, may contribute to the weakening and thinning of the cornea, increasing the risk of keratoconus.
  • Oxidative Stress: The cornea is exposed to high levels of ultraviolet light and oxygen, which may lead to oxidative stress and tissue damage, potentially resulting in keratoconus.
  • Connective Tissue Disorders: Conditions such as Ehlers-Danlos syndrome and Marfan syndrome, which affect the body’s connective tissue, can increase the risk of developing keratoconus.

Recognizing the Symptoms of Keratoconus

Keratoconus typically presents with a range of symptoms that may progressively worsen over time. Some common signs and symptoms of keratoconus include:

  • Blurred or Distorted Vision: As the cornea bulges and thins, light entering the eye is refracted improperly, resulting in blurred or distorted vision.
  • Increased Sensitivity to Light: The irregular curvature of the cornea may cause increased glare and sensitivity to light, often causing discomfort in bright environments.
  • Frequent Prescription Changes: Individuals with keratoconus may experience rapid changes in their eyeglass prescription as the condition progresses.
  • Difficulty Wearing Contact Lenses: The irregular shape of the cornea may render standard contact lenses uncomfortable or ill-fitting, posing a challenge for those affected by keratoconus.

Early detection and intervention are essential for effectively managing keratoconus and preventing significant vision loss.

Diagnosing and Monitoring Keratoconus

Diagnosing keratoconus involves a thorough eye examination, conducted by an experienced eye care professional, to assess the cornea’s shape and thickness. Diagnostic tests commonly used to evaluate keratoconus include:

  • Slit-Lamp Examination: The eye care professional uses a slit-lamp device to examine the cornea’s structure and integrity, looking for signs of thinning, scarring, or irregularities.
  • Corneal Topography: This test maps the cornea’s surface, providing detailed information about its curvature and shape to help assess the presence and extent of keratoconus.
  • Pachymetry: This measurement of corneal thickness helps determine the severity of keratoconus and aids in treatment planning.

Consistent monitoring of keratoconus through regular eye examinations is essential for tracking the disease’s progression and adjusting treatment plans accordingly.

Treatment Options for Keratoconus at Valley Laser Eye Centre

At Valley Laser Eye Centre, our team offers a variety of tailored treatment options for individuals affected by keratoconus, including:

  • Eyeglasses and Soft Contact Lenses: In the early stages of keratoconus, eyeglasses and soft contact lenses may suffice to correct vision issues resulting from the irregular corneal shape.
  • Specialty Contact Lenses: As the condition progresses, specially designed contact lenses, such as rigid gas permeable lenses, hybrid lenses, or scleral lenses, may provide optimal vision correction and comfort.
  • Corneal Collagen Cross-Linking (CXL): This minimally invasive procedure strengthens the cornea by creating new connections between collagen fibers, slowing or stopping the progression of keratoconus.
  • Corneal Transplant: In severe cases of keratoconus where other treatment options have proven unsuccessful, a corneal transplant may be necessary to replace the damaged cornea with healthy donor tissue.

Our eye care professionals will thoroughly evaluate your eye health and the severity of your keratoconus, recommending an individualized treatment plan designed to preserve your vision and optimize your comfort.


Keratoconus is a progressive eye condition that can cause significant vision impairment if left undetected and untreated.
